METHOD AND DEVICE FOR PRODUCING SPHERICAL PARTICLES FROM LIQUID PHASE

Production of polymer particles in powder form using an atomization technique

A process for producing spherical polymer particles which may be either monodisperse of a predetermined and controlled size, or polydisperse, using a liquid atomization technique. The process includes an aerosol generator to create a stream or multiple streams of liquid droplets sprayed into a thermal reactor. The aerosol generator sprays the feed solution which comprises liquid organic monomers or semi-polymerized monomers, a polymerization catalyst and optionally, a solvent, into the thermal reactor environment. The solvent evaporates allowing polymerization reactions to commence. Polymerization may proceed by a variety of methods. Polymerization is completed during the flight-time of the droplets and the solid polymer particles are collected at the bottom of the reactor. The size of the particles in every batch may be predetermined and controlled by fine tuning the aerosol generator's configuration or operational parameters to adjust the size of the droplets of the feed solution being sprayed into the reactor. In one variation, the feed solution to the aerosol generator may be a polymer dissolved in an appropriate solvent. The aerosol generator then sprays the polymer solution in the thermal reactor to generate particles by evaporating the solvent.

固体颗粒，生产其的方法和装置

本发明涉及由可流动的原材料(2)和固体部分制成的固体颗粒(10)，并涉及其生产方法，其中可流动的原材料(2)分成滴(9)，沿轨迹(50)将所述滴(9)引入固化液体(11)中，其中它们以固体颗粒(10)的形式固化。本发明的特征在于，使用固化液体(11)，并且如果可流动的原材料(2)含有锕系元素氧化物，那么所述固化液体稳定地流动，从而能够生产具有更大球形度和窄的粒径分布的固体颗粒。
